Contractors are responsible for providing all equipment, materials, and services necessary to produce a complete and fully operational system, including coordination with other trades, protection of the historical site during construction, mandatory archaeologist monitoring, soil erosion and sedimentation control, and compliance with all applicable state and federal codes and regulations.

Bidders must be Michigan-based businesses or demonstrate significant business presence in Michigan and must provide proof of State Project Registration from the Department of Labor and Economic Opportunity.

Liquidated damages are assessed at $750 per calendar day for delays beyond the substantial completion date of September 30, 2026. While no incumbent vendor or existing contractor is identified in the solicitation documents, the project requires extensive coordination with the Mackinac Historic State Parks Team and mandatory archaeologist monitoring to protect historical artifacts and displays at the Colonial Michilimackinac site.
